When nearby construction disturbs a spiritual resting place, its disgruntled denizens do what any supernatural being would do after a rude awaking - they terrorize the local school.

And that means it's up to a scruffy band of young ghost hunters to expel their satanic schoolmates before everyone gets sent to permanent detention! Meet Satsuki, her crybaby brother, the resident class stud, the school nerd and "psychical researcher," a born-again beauty, and a resentful, demon-possessed cat in the funniest, scariest school you've ever enrolled in.
